    The annual output of filtered mercury (Hg) from Lesni potok catchment, a forested ecosystem in central Europe, was estimated at 0.87 lg m-2. More than 70% of the annual mercury output flux occurred during the spring snowmelt period. The snowmelt period is the most important part of the hydrological year in central European forested ecosystems. Average filtered concentrations of mercury (17.8 ng L-1) and DOC (10.5 mg L-1) in the stream water during snowmelt were greater than average values for the rest of the hydrological year. Omitting frequent daily or bi-daily filtered mercury analysis during the snowmelt caused underestimation of the annual mercury output flux (0.79 lg m-2) and decreased the accuracy of flux calculations.
